Hi! I have an older set of arrows I don't use for 70m since switching to heavier recurve limbs. I use them for blank bale practice though, since aiming is not an issue and I don't want to use my good set. I only used the fletched ones so far and it occured to me that I can shoot the unfletched ones as well.

Or is there something I'm missing and should not use the unfletched ones for blank bale 3m shooting?
